Activities

CLS is constantly looking for new partners for its regional modelling initiative.

CLS is recognised as a world leader in the field of operational Satellite Oceanography. It has substantial expertise in the fields of instrument calibration, data quality control, data merging and the elaboration of sophisticated derived products. CLS also has recognised expertise in the field of data assimilation and model validation, principally acquired through its on-going collaborations with Mercator Ocean.
In the field of regional modelling, CLS has developed the following activities:

  • Regional model specification
  • Model configuration validation
  • Data assimilation
  • Inter-comparison of model output (3D fields)
  • Model/data comparison
  • Post processing and diagnostics.

These activities involve the development of novel numerical methods which can be used in every part of the world with every type of ocean model. These methods rely on a host of products which include:
  • 2D products:
    • SST (sea surface temperature):
      The models SST field is compared to satellite SST from various sources such as the NOAAA pathfinder high resolution data.
    • SSH (sea surface height):
      The model SSH height is compared to satellite observations which come from the SSALTO/DUACS system, developed and maintained at CLS.
    • Surface currents:
      SURCOUF combines an estimation of the geostrophic currents and the wind driven ones to provides weekly estimation of surface currents. These can then be compared to the model U and V data fields.
     
  • 3D products:
    • Temperature and salinity:
      T and S fields from the models are compared to the climatologies and the ARMOR 3D data base in order to evaluate the model's representation of water masses.
     
  • In situ data:
    • Current meters:
      Current measurements from Acoustic Doppler Current Profilers (ADCP) and Rotor Current Meters (RCM) are compared to model data. The issue of co-location and representation of the bathymetry in the model as well as vertical averaging are particularly important for such comparisons. The issue of tidal currents is also non trivial.
    • Tide gauges:
      Measurements of such Sea Level Stations are compared to model output.
CLS prides itself on its ability to deliver complex scientific results in the format best suited to its customer/partners needs. Furthermore, its unique position allows it to offer products developed by the research community with industrial specifications and standards.
